Display device, display program storage medium, and display method

Abstract

A display device includes: a data acquisition section which acquires plural data with which dates and/or times are associated; and a date and/or time acquisition section which acquires dates and/or times associated with the plurality of data. The display device further includes: a data classification section which classifies the plural data to plural groups which belong to plural time regions which do not overlap with each other, based on the length of intervals between the dates and/or times acquired by the date and/or time acquisition section; and a display section which classifies plural icons which show the plural data to the groups and displays the plural icons.

1 . A display device comprising:
 a data acquisition section which acquires a plurality of data with which dates and/or times are associated;   a date and/or time acquisition section which acquires dates and/or times associated with the plurality of data;   a data classification section which classifies the plurality of data to a plurality of groups which belong to a plurality of time regions which do not overlap with each other, based on the length of intervals between the dates and/or times acquired by the date and/or time acquisition section; and   a display section which classifies a plurality of icons which show the plurality of data to the groups and displays the plurality of icons.   
   
   
       2 . The display device according to  claim 1 , wherein
 the data is image data which represents images of subjects and with which the image pick-up dates and/or times of the images are associated, and   the date and/or time acquisition section acquires the image pick-up dates and/or times.   
   
   
       3 . The display device according to  claim 1 , wherein the data classification section classifies the plurality of data to the plurality of groups based on a relative length of intervals between the dates and/or times acquired by the date and/or time acquisition section. 
   
   
       4 . The display device according to  claim 1 , wherein when the data classification section classifies the plurality of data to the groups, the data classification section time-sequentially confirms intervals between the dates and/or times associated with the data, and the two data, with which are associated two dates and/or times across an interval whose length is changed in excess of a predetermined degree with respect to an interval immediately before the interval, are classified to different groups. 
   
   
       5 . The display device according to  claim 1 , wherein the display section displays a three-dimensional space having an axis of the groups and disposes the icons of the data to the position of the group, to which the data is classified, on the three-dimensional space. 
   
   
       6 . The display device according to  claim 1 , comprising an auxiliary display section which displays a two-dimensional space having an axis of the groups and disposes a mark to the position corresponding to a group to which the data is classified on the two-dimensional space to show that data exists in the group. 
   
   
       7 . The display device according to  claim 6 , further comprising:
 a designation section which designates a group on the two-dimensional space by displaying a designation frame along an axis different from the axis of the groups on the two-dimensional space, and moving the designation frame along the axis of the groups; and   a display control section which causes the display section to dispose the icons in a three-dimension display space with the group designated by the designation section displayed on a foremost surface.   
   
   
       8 . The display device according to  claim 7 , further comprising a data number display section which displays the number of data classified to the group designated by the designation section. 
   
   
       9 . The display device according to  claim 1 , wherein the data acquisition section acquires the plurality of data from a storage section in which the plurality of data is stored. 
   
   
       10 . A display program storage medium which stores a display program which is executed and constructs in a computer:
 a data acquisition section which acquires a plurality of data with which dates and/or times are associated;   a date and/or time acquisition section which acquires the dates and/or times associated with the plurality of data;   a data classification section which classifies the plurality of data to a plurality of groups belonging to a plurality of time regions which do not overlap with each other, based on the length of intervals between the dates and/or times acquired by the date and/or time acquisition section; and   a display section which classifies a plurality of icons showing the plurality of data to the groups and displays the icons.   
   
   
       11 . A display method comprising:
 a data acquisition step which acquires a plurality of data with which dates and/or times are associated;   a date and/or time acquisition step which acquires the dates and/or times associated with the plurality of data;   a data classification step which classifies the plurality of data to a plurality of groups belonging to a plurality of time regions which do not overlap with each other, based on the length of intervals between the dates and/or times acquired in the date and/or time acquisition step; and   a display step which classifies a plurality of icons showing the plurality of data to the groups and displays the icons.
